*Stata did not provide the CI because there were no subjects on ARV in those without PTB-HIV co-infection
**All predictors with p<0.20 were considered for inclusion in the final model. Adjusted ORs for predictors that remained in final model are shown. Chronic diarrhoea and viral load dropped out as significant predictors in the final model.
